The objective of this study was to compare the contact tightness that is achieved with these two matrix band systems when using composite material. Methods: A total of 30 patients, i.e., 60 cavities were selected in this quasi-experimental study. Patients with two cavities in ...
with great expectations for the future.These materials are called advanced compositematerials and will be used to replace some of themetals currently used in aircraft construction.Advanced composites are materials consisting ofa combination of high-strength stiff fibers embeddedin a common matrix (binder...

Composite structures refer to engineered materials composed of two or more constituent materials with different properties. These constituent materials, known as the matrix and reinforcement, work together to create a composite material that exhibits enhanced mechanical, thermal, or electrical properties comp...
